KELAIWEI cooperates with Professor Sun Xiaogang of Nanchang University, relying on the advanced technology accumulated by Professor Sun Xiaogang's expert team for more than 20 years, has applied for more than 100 patented technologies in total, 9 state-authorized invention patents our company relies on advanced technology to independently research and develop production equipment, build production base and train production technicians to realize the full-automatic chemical industrial production of whisker-like carbon nanotubes mass production and the absorption rate of carbon nanotubes.
Synthesis of carbon nanotubes by hydrothermal method. Put the acidic solution of sucrose (according to the ratio of 1 to 19, and mix it with h2so4-sucrose solution) into the reaction kettle, and cool it to the indoor temperature after the reaction of 180 degrees high temperature within 12 hours, after centrifugal separation, ionized water is removed, and after washing and drying, carbon nanotubes of 1 nanometer to 2 nanometer length can be obtained.
Henan KELAIWEI Nano Carbon Material Co., Ltd. Pays attention to technological research and development, rewards scientific researchers with great money for their research results, and quickly realizes technological transformation and carries out industrialized mass production. Our company pays attention to the cooperation with the top experts of domestic scientific research institutions, and strives to break the foreign technology monopoly of high-end nanomaterials industry. Through technological innovation, large-scale industrial mass production of whisker carbon nanotubes has been first realized by our company.
The technological achievements of Henan KELAIWEI Nano Carbon Material Co., Ltd are continuous. Under the leadership of Professor Sun, the chief engineer of KELAIWEI's technical team, once again obtained the technical patent in the synthesis of whisker carbon nanotube materials. It is reported that the technical patent number obtained this time is "ZL201210304345.7". The technical name is "automatic and continuous production of whisker carbon nanotubes synthesis device".
High capacity lithium ion battery is the negative electrode material of lithium ion battery, which requires high capacity. At present, silicon carbon negative electrode material is generally used, and silicon carbon negative electrode will generally expand to a large extent when used, resulting in poor cycle performance of the battery, taking advantage of the length advantage of whisker carbon nanotubes, the conductive network can still be maintained when the silicon carbon negative electrode material expands, and the cycle performance of the battery is improved. At present, KELAIWEI is cooperating with X company in developing the capacity negative electrode, increase the capacity and cycle performance of the negative pole, and the absorption rate of carbon nanotubes.
A far infrared electric floor heating Manufacturing Co., Ltd. in Shandong has been engaged in electric floor heating manufacturing for more than four years, and even the products with high electric heating conversion bit point can not only save energy, but also reduce the application of products, thus saving production costs. After five on-site visits, the company finally chose the far infrared paper produced by Henan KELAIWEI Nano Carbon Material Co., Ltd. as the only supplier of its far infrared paper.
Carbon nanotubes are used in the manufacture of PI heating film for CNT batteries. The PI heating sheet made of two-layer polyimide film by pressing carbon nanotube conductive film at high temperature benefits from the ultra-high conductivity, very strong toughness (100 times of steel strength) and thermal conductivity of carbon nanotubes, it has strong flexibility and thermal conductivity, and its quality is very, very light. Henan KELAIWEI Nano Carbon Material Co., Ltd. is looking for powerful companies to carry out cooperation.
